摘要： An electrode (110) for an electrochemical cell, comprising a conductive, porous, hydrophilic, gas-permeable and a liquid-permeable liquid-side layer (111) having a liquid-facing side (116), and a non-conductive, porous, hydrophobic, gas-permeable and liquid-impermeable gas-side layer (112) having a gas-facing side (117). Gas-producing electrochemical reactions are promoted at an interface (115) between the liquid-side layer (111) and the gas-side layer (112) by a beneficial relationship of capillary pressures of the electrode layers. The liquid-side layer (111) exhibits a repulsive capillary pressure in the liquid electrolyte (113) of the cell (110) and the gas-side layer exhibits an attractive capillary pressure in the liquid electrolyte (113).
